Adenomas of the colon and rectum

Reliability of routine double-contrast examination (DCE) of the large bowel in polyp detection: A prospective clinical study

“…The potential diagnostic capacity of this method was later confirmed [33-36, 50, 51, 56]. The DCE technique proved capable of detecting even small polyps (5 mm across), which, in combination with colon- scopy meant that practically all such neoplasms could be detected and treated [14,15,28,29,50,51]. Despite these advantages, DCE is still not used in many hospitals.…”

“…Owing to the outstanding results of colonoscopy in the detection and treatment of small lesions, the method tends to replace radiographic examination of the colon [15,56]. This can be explained on the basis of the technique used in many radiology departments, one based on contour diagnostics, when appropriate, combined with compression spot films [56,57].…”

“…Because patients with precancerous lesions of the large bowel have no characteristic symptoms [6,14], sigmoidoscopy has been especially recommended as a supplement to a complete physical examination [13][14][15][16]. Such an approach could ensure detection of 50% of all benign polyps ( Fig.…”

“…Also, colonoscopy has some diagnostic and technical limitations [24][25][26][27]. Because every 5th patient with neoplastic disease of the large bowel has more than 1 benign or malignant tumor elsewhere in the colon, it is imperative that the bowel be examined meticulously [14,15,28,29].…”
